Ecology: The Experimental Analysis of Distribution and AbundanceThis book is not an encyclopedia of ecology, but an introduction to its problems. It is not descriptive ecology, and will not tell students about the ecology of the seashore or the ecology of the alpine tundra. It approaches ecology as a series of problems, problems that are confined neither to the seashore nor to the alpine tundra, but are sufficiently general to be studied in either area. |
